These regulations stipulated, among other things, that proprietary institutions that claim to provide career training need to furnish proof that their graduates found "gainful employment," defined in terms of a reasonable debt-to-income ratio and the ability to repay loans on time. The regulations were finally enacted—among much protest from for-profits—last year.

Now the Obama administration wants to add to for-profits' tribulations by closing loopholes in the current "90/10" rule, a federal law mandating they receive no more than 90 percent of their funding from federal student aid programs.

It seems that some for-profits have used loopholes that allow them to get more than 90 percent—because just 90 percent is insufficient—of their funding from the federal teat. Funding that is usually loans. And these loans, lest I remind you, often go unpaid.

"To be very clear," says Duncan, "this is taxpayer dollars. This is your money."

You and I, my friends, are just handing cash over to the University of Phoenixes of the world, because they can't even manage to get 10 percent of their funding from anyone but us. We might as well be saying, Hey, I trust you will use this to make yourself rich and put people from vulnerable populations in massive debt, all in the name of an education that promised to give them a shot at a better life but is 100 percent doing the opposite.

To be fair, even heavily endowed nonprofit universities and colleges in the United States get a portion of their funding from Uncle Sam, but not nearly as much.

For-profits game the 90/10 rule in ways that are particularly "unconscionable," as Duncan put it when we spoke. He explained that they were able to exploit a loophole by carving out their own "GI Bill," which in their case meant they didn't count federal student aid toward the 90 percent ceiling if it went to combat veterans of the U.S. armed forces.

Those veterans, Duncan says, have "become this unbelievably valuable target. I'm not anti-for-profit if they're doing a good job. But if they're exploiting people … to do that to veterans, how do you sleep at night?"

But however enraged we are, what can we do? Even given the level of influence the for-profit lobby has in Washington, perhaps we can aim a little higher than just subjecting these folks to the crippling regulatory indignity that is getting a whole tenth of their money from somebody other than Jane Q. Me.

Perhaps we could require new advertising regulations that put proprietary education providers in the same category as pharmaceutical companies, so that their ads would consist of 15 seconds of soaring platitudes and 45 seconds of hushed and hurried disclaimers: Suxxe$sTech Institutes may cause mild to moderate inability to transfer credits to a legitimate institution, uncontrollable head-shaking by hiring managers, and a sudden increase in negative income.

I mentioned this brilliant idea to Duncan, and he thought it was sort of funny but suggested instead that what the for-profits need is some "skin in the game": accountability to the outcomes they promise. "At the end of the day, money talks with these guys," he says.

If successful graduates of a particular certificate or degree program don't secure work in the field that was promised to them, taxpayers shouldn't be on the hook. "What if [the for-profits] had to pay back those loans?" Duncan asks. "They have to have a financial incentive to do the right thing. Absent that, they will game the system."

The Corinthian group's shutdown is a good start, but thousands of other unscrupulous for-profits are still peddling fake educations to vulnerable populations, and all on our dime. While members of Congress and state legislators are busy trying to police the meager food-stamp budgets of the poor, or else micromanaging the course loads, tenure, or "effectiveness" of a few hundred professors who make less money than my UPS guy, the for-profits are making billions—billions—off of loans they know will go bad.

"The status quo is indefensible," Duncan says. "The fact that so much taxpayer money is going behind this makes no sense to me."

That, good sir, would be because it makes no sense at all. Now that Corinthian has fallen into a lake of fire under the brunt of regulations that are still far too lax, will similar institutions change their recruitment practices or curricula to avoid similar fates? Or, as Duncan suggests, will nothing change until the industry is responsible for every cent its unemployable graduates borrowed, most of which went to the CEOs' seven-figure salaries?
